Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3198, here are decompositions:

7 + 3191 = 3198
11 + 3187 = 3198
17 + 3181 = 3198
29 + 3169 = 3198
31 + 3167 = 3198
61 + 3137 = 3198
79 + 3119 = 3198
89 + 3109 = 3198

Showing the first eight; more decompositions exist.
